The Best 223 Suppressor for Making Your “Modern Sporting Rifle” Better for Self-Defense

Last Updated on January 12, 2021.

An AR-15 and other semi-automatic .223 rifles make excellent self-defense platforms. They’re usually reasonably compact, easy to shoot, and have plenty of power for defensive shooting.

And, since you’ll rarely (if ever) be wearing hearing protection if you need to use your .223 rifle for self or home-defense, a suppressor is an excellent self-defense muzzle device.

And it’s not just about your hearing. The concussion of shooting a rifle inside a house can be disorienting. So a suppressor can make you more efficient with your defensive rifle.

You also get tons of cool guy points for having a suppressor on your gun.

1. SilencerCo Omega Suppressor - Overall Best 223 Suppressor

The SilencerCo Omega Suppressor is one of the best selling suppressors in the world because it’s one of the best performing suppressors on the market. And it’s priced well enough that most people can afford this suppressor.

The main thing is sound suppression. And this suppressor delivers on that front. It’s capable of making everything from a 5.7mm to a 300 Winchester Magnum hearing safe. So it’s more than enough for a .223 round.

But, it’s also relatively compact. This suppressor is only 7.09 inches long. It only adds about 5 inches of length to your rifle. So you still get most of your rifle’s maneuverability with this suppressor on the end.

And this suppressor uses a titanium tube and stellite baffles for exceptionally long service life and minimal cleaning requirements.

The construction is also lightweight. This suppressor weighs just 14 ounces.

Lastly, the included Anchor Brake muzzle cap reduces felt recoil and makes your rifle shoot extremely soft. So you get more control.

The only real downside is the muzzle device compatibility. There are only 2 muzzle devices that are compatible with the SilencerCo quick detach system. They’re good muzzle devices (the muzzle brake is included, and it works well). But the muzzle device options are a bit limited.

However, this is still an outstanding suppressor that’s perfect for a defensive rifle. But you could easily put this suppressor on a bolt-action or any other rifle and be happy with it.


  • Makes everything from a 5.7mm to a 300 Winchester Magnum hearing safe.
  • Quite compact considering the sound suppression. Only adds about 5 inches to the end of your barrel.
  • Titanium tube and stellite baffles give exceptionally long service life and require little cleaning.
  • Muzzle brake end cap gives you great control over your shots.
  • Full-auto rated.


  • Flat end cap sold separately.
  • Only compatible with 2 muzzle devices.

2. OSS BPR26 5.56 Auto Suppressor - Full-Auto 223 Suppressor

Full-auto rifles are hard to come by for civilians. But there are benefits to having a full-auto rated suppressor. And the OSS BPR26 5.56 Auto Suppressor delivers these benefits plus a few extras.

But, before we talk about full-auto, let’s clarify that this suppressor does it’s primary job quite well. The sound level of a 5.56 is 136 decibels, which is hearing safe. So this suppressor protects your hearing the way it should.

Now for the full-auto stuff.

This suppressor is (obviously) full-auto rated

But the thing that makes it nice for fully-automatic and sustained rapid fire is the helix end cap, which reduces back pressure and blows less gas in your face. So it’s much more comfortable to shoot than some other suppressors without any modifications to your rifle.

The end cap also functions as a flash hider and muzzle brake to reduce your visual signature and give you more control over your shots.

And it’s just 8 inches long. It’s not the shortest suppressor on the market. But it’s still fairly compact.

However, this OSS suppressor is a bit heavy. It weighs 21.5 ounces. So you’ll feel it out on the end of your muzzle.

But the performance is solid. And it keeps gas out of your face so you can keep your eyes on your target.


  • Makes 5.56mm rounds hearing safe.
  • Full-auto rated.
  • Helix end cap blows less gas in your face.
  • End cap also works as a flash hider and muzzle brake for less visual signature and more control over your shots.
  • Fairly compact.


  • Heavy.

3. Dead Air Armament Sandman-K Suppressor - Compact 223 Suppressor

The Dead Air Armament Sandman-K Suppressor is by far the best performing suppressor of its size. There just aren’t any other suppressors that are this short and offer as much sound suppression.

This suppressor is just 5.4 inches long and delivers enough sound suppression to make .223 rounds hearing safe. The sound level measures at about 138 or 139 decibels for most rifles, which is just below the hearing safe threshold.

It only adds 2.9 inches to the overall length of your rifle. That’s a lot of sound reduction per inch! And there’s no minimum barrel length restrictions on this suppressor. It’s perfect for anyone who wants to keep their rifle compact, even when it’s suppressed (or keep a long gun from being ridiculously long).

This suppressor is built with stellite baffles, which last longer and require less cleaning than inconel baffles. So it lasts a long time and is simple to use.

Lastly, this suppressor is full-auto and magnum caliber rated. It will handle everything up to a 300 Winchester Magnum. However, it’s not quite strong enough to make larger magnum cartridges hearing safe.

There are suppressors out there that offer better sound suppression. But there are very few suppressors that offer this much sound suppression in such a short form factor. If you need a short suppressor that still protects your hearing, this suppressor is the only way to go.


  • Makes .223 rounds hearing safe.
  • Extremely compact. Adds just 2.9 inches to the overall length of your rifle.
  • Stellite baffles are extremely long lasting and easy to maintain.
  • Rated for full-auto and magnum calibers up to 300 Win Mag.


  • Compact size limits sound suppression. Just barely makes .223 rounds hearing safe.
  • Not strong enough to make magnum calibers hearing safe.

4. Sig Sauer SRD556Ti-QD Suppressor - Budget 223 Suppressor

Sig rarely makes anything that qualifies as a “budget” option. However, the Sig Sauer SRD556Ti-QD Suppressor is both surprisingly capable and surprisingly affordable.

First, it attenuates the sound of a .223 round down to 134 decibels, which is well within hearing safe limits.

But it’s still only 6.8 inches long. It’s not the most compact suppressor available. It offers an excellent size to sound reduction ratio, though.

Additionally, the tubeless titanium construction is ridiculously durable. This suppressor is virtually indestructible.

And the quick detach system offers a tight lockup that delivers a minimal shift in point of impact. Most shooters notice about a 2 MOA shift in point of impact. Some suppressors offer less point of impact shift. But the shift from this suppressor is totally manageable.

Unfortunately this suppressor is not user serviceable. It is serviceable. But you’ll need to send it back to Sig or have a gunsmith service your can.

However, this Sig Sauer suppressor is still one of the best for the money on the market. It’s tough to find suppressors that are this quiet and this compact for this price. So this is a good option for anyone looking to maximize their gun budget.


  • Brings .223 rounds well within hearing safe range.
  • Fairly compact, with excellent sound suppression for the size.
  • Tubeless titanium construction is super durable and long lasting.
  • Quick detach system is very easy to use and gives a fairly minimal point of impact shift.


  • Not user serviceable.
  • 2 MOA point of impact shift is decent. But some suppressors have less effect on the point of impact.

5. AAC SR7 Suppressor - Value 223 Suppressor

The Advanced Armament SR7 Suppressor is essentially the 7.62 model of their popular AAC SR5 suppressor. However, the SR7 is usually in stock. And it’s a multi-caliber suppressor, which makes it more cost efficient.

And the sound attenuation of this suppressor is excellent. It easily brings a .223 round into the hearing safe range. It’s also capable of suppressing 7.62mm, 300BLK, and other common rifle rounds. So you can throw this suppressor on a lot of guns.

The AAC ratchet quick detach system is also excellent. It’s super easy to attach and detach this suppressor. And the quick detach system locks up very securely. The point of impact shift with this suppressor is typically about 1.5 MOA, which is less than many competing suppressors.

Lastly, the blast baffle on this AAC suppressor is specially designed to reduce wear and erosion more than other blast baffles. So this suppressor is an especially good option if you have a short-barreled rifle, since it holds up to the gas corrosion better.

Since this is a multi-caliber suppressor, it’s a tad longer than some dedicated .223 suppressors. However, it’s only 7.6 inches long, which is just an inch longer than the SR5.

You don’t give up much maneuverability to get a suppressor that will work on a lot of rifles. And the price is hard to beat.


  • Capable of suppressing 7.62mm and other larger calibers, in addition to .223 rounds.
  • Quick detach system is quick and easy to use.
  • Minimal point of impact shift.
  • Specially designed blast baffle enhances corrosion resistance for better short-barreled rifle compatibility.


  • About an inch longer than most dedicated 5.56mm suppressors.

6. NEMO Arms Elite-FA-QD 5.56 NATO Suppressor - Best 223 Suppressor for the Money

The NEMO Arms Elite-FA-QD 5.56 NATO Suppressor is an affordable suppressor that performs well in just about every aspect, though it’s not the best in any particular area.

First, the sound attenuation is enough to bring a .223 round well within hearing save levels. However, it’s also just 7 inches long.

It has better sound suppression than most compact suppressors. But it only adds about 5 inches to the overall length of your rifle. So it’s a good mix of compact size and sound attenuation.

Additionally, this suppressor comes with one of the best quick detach muzzle devices availableThe included 3-lug flash hider looks cool and works quite well as a standalone muzzle device.

And it locks up very securely for a 3-lug system. There’s no wobble, and the point of impact shift is very minimal (less than 2 MOA). The 3-lug attachment on this suppressor is almost as good as the Dead Air Armament KeyMount system, and that’s saying something.

Lastly, this suppressor is full-auto rated. So you can run this suppressor pretty hard.

This suppressor is a tad more expensive than other budget suppressors. But the price is very good for a suppressor that delivers such good all-around performance. So the value for the money is excellent.


  • Brings the report of a .223 round well within hearing safe levels.
  • Reasonably compact, only adds about 5 inches to the overall length of your rifle.
  • The 3-lug quick detach system provides a remarkably secure lockup.
  • Included quick detach flash hider muzzle device is excellent.
  • Full-auto rated.


  • A tad more expensive than some other budget and value suppressors. But the all-around performance is very strong.

7. Surefire SOCOM556-RC2 Suppressor - Tactical 223 Suppressor

There’s just no way I could leave the Surefire SOCOM556-RC2 Suppressor off the list. It’s the official selection of the U.S. Special Operations Command. So it’s got a lot of street cred right off the bat.

This suppressor brings the report of a .223 round below 140 decibels. It’s not THE BEST sound suppression. But it meets the requirements of the military contract. And it’s hearing safe.

However, this suppressor is just 6.2 inches long. Even though the sound suppression isn’t the best, it doesn’t add much to the overall length of your rifle. So it’s a good option for 10.5, 11.5, and 12.5 inch builds.

The baffles and end cap are also designed to minimize gas blowback and reduce muzzle flash. So it reduces your audio and visual signature.

Of course it’s full-auto rated. And it’s got a really high heat toleranceThis suppressor is a good option for those who like to train hard with their suppressed rifle.

And the quick detach system delivers a remarkably secure lockup and a very minimal point of impact shift. The point of impact shift is also consistent. So the change in performance from unsuppressed to suppressed shooting is predictable.

All in all, this Surefire suppressor delivers excellent performance and durability. It’s pretty expensive though. But, if you can afford it, this is an excellent suppressor for hard use on short-barreled rifles.


  • Reduces sound level of a .223 round to below the hearing safe threshold.
  • Very compact. Adds very little overall length to your rifle.
  • Baffle design and end cap minimize blowback and muzzle flash.
  • Full-auto rated.
  • Quick detach system is fast, easy to use, and keeps point of impact shift to a minimum.


  • Sound suppression could be better.
  • Expensive.

SilencerCo Omega
